Rancho RS9000XL 0″ Front Lift Shocks for 1999-2004 Ford F-550

Part Number: RS999267

Summary: The Rancho RS9000XL series is the industry benchmark for adjustable damping control, specifically engineered for heavy-duty applications like the Ford F-550. Featuring a 9-position manual tuning knob, these shocks allow owners to instantly transition between a soft street ride and the firm control required for heavy towing or hauling. Designed for vehicles at stock height, these shocks provide a custom-tailored suspension response to eliminate the “one size fits all” compromise of standard dampers.

Features

• 9-Position Tuning: A manual adjustment knob provides nine distinct levels of damping force to ensure the perfect ride quality for varying load capacities.
• Large Diameter Body: The 2.75-inch heavy-duty body provides increased fluid capacity to ensure cooler operating temperatures during sustained heavy-use cycles.
• Nitrogen Gas Charged: High-pressure gas integration provides a reduction in aeration and foaming to ensure consistent damping performance in demanding environments.
• Protective Boot: A durable liquid-metallic finish and included polyvinyl boot provide an extra layer of protection for the shock rod to ensure long-term seal integrity.

Frequently Asked Questions

How do I adjust the settings on these shocks?
These shocks feature an external 9-position knob located at the base of the shock body. You can manually turn the dial to increase or decrease firmness without any tools.

Will these shocks lift my Ford F-550?
No, these shocks are configured for a 0-inch lift. They are designed to replace factory-length shocks and do not provide any additional lift height.

What setting should I use for towing?
While preference varies, it is generally recommended to use a higher setting (7-9) when towing or hauling heavy loads to improve stability and reduce vehicle porpoising.
